i want to achieve a round strip led lights at the bottom inside of a container with glass shader in order to light up the whole glass
If you want to do it all with a shader, you could do something like this. All I did was make some vertical stripes with a Wave texture (I isolated the X and Y and normalized them so there would be 2 &quot;banks&quot; of LED's). All I did after that was make a mask for where the lights will go (vertically) and use that as a mix factor between a Glass Shader and an Emission shader that is colored by the &quot;lights&quot; I made with the Wave Texture.

If you darken the ambient lighting, you can see it lights up the glass. You can increase the light propagation by increasing the roughness of the Glass Shader slightly, you can also increase the IOR - however, the proper IOR for glass is 1.45 - too high a value, and things will start to look unrealistic, especially from certain angles. Find a balance that works best for you.
Lastly, you can increase the emission strength, but also beware that too strong a value may start to &quot;wash out&quot; some of the colors.
